Bosch 10-Piece Titanium Coated Drill Bit Set

Model TI10

Titanium drill bits last 6X longer than black oxide bits
The durability comes from the super hard titanium nitride coating
The hardness of the titanium coating protects the bits from chipping and cracking, while the lubricity protects from heat build up, which is the number one cause of product failure
Surface hardness in excess of 80 HRC allows for penetration of tough materials including common stainless steel
The speed helix design penetrates 3X faster than standard bits
The benefits include easier drilling, reduced heat, extended drill bit life, and extended cordless battery life
135° split point starts on contact with no walking or skating and no center punch is required
